Research progress on irradiation stability of perovskite solar cells for space applications

Perovskite solar cells (PSCs) are promising for space applications owing to their high efficiency, superior power-to-mass ratio, and notable radiation tolerance. However, the impact and mechanism of the space radiation (e.g., protons and electrons) on their performance remain poorly understood, impeding the advancement of their space capabilities and applications. This review summarizes recent advances in understanding the irradiation stability of PSCs under simulated space conditions. Firstly, the review analyzes the impact of different space radiation particles. Subsequently, we detail the radiation response of perovskite materials, reveal the mechanisms of radiation-induced damage, and summarize strategies for improving stability. Finally, the review concludes with perspectives on future research directions, highlighting the study of coupled environmental effects, long-term reliability assessments, and the development tandem cell configurations.
